Deviation of ureter

This code describes an anatomical abnormality where the ureter deviates from its normal course or position. This deviation can be congenital or acquired, often resulting from extrinsic compression, adhesions, or an underlying mass. It signifies an altered path of urine flow from the kidney to the bladder.

This code is appropriate when documentation indicates an abnormal positioning or curvature of the ureter, such as a kinked, tortuous, or displaced ureter. It is often identified during imaging studies like CT scans, MRIs, or intravenous pyelograms (IVP) performed for urinary tract symptoms or as part of workup for other abdominal/pelvic conditions.

• Do not use this code for ureteral strictures or obstructions; those have more specific codes.
• Ensure documentation clearly states "deviation" or describes an abnormal course of the ureter, rather than just a dilated or compressed ureter without an explicit positional change.
• Consider additional codes for any underlying cause of the deviation (e.g., tumor, retroperitoneal fibrosis) or any resulting complications (e.g., hydronephrosis).
